Mechanisms of Fretting Fatigue Crack Initiation in Medium Strength Steels.

Abstract

Effects of carburization and decarburization were studied on the fretting fatigue behavior of a medium carbon steel at room temperature. Tests were conducted in room air in a listing frame which was designed to vary the fretting (normal) load, and the relative displacement (slip amplitude) between the list specimens and fretting pads. Statistical studies conducted on the specimens indicated that after a threshold value of normal load, the fretting fatigue lives dropped by an order of magnitude. No significant effects of slip amplitude or fretting wear were observed on the fretting fatigue life. (Author)
